无机框图推断题具有综合性强,能力要求高的特点。该题型以元素化合物的特殊性质为突破口,以物质之间的转化关系为主要载体,可以将基本概念、基本理论、化学实验、简单化学计算等有机结合起来进行考查。在高三复习中抓好无机推断题,不仅能进一步加深对元素化合物的有关知识的认识,还能培养获取信息、整合信息、分析问题和解决问题的能力。解决无机框图推断题的一般流程是:整体浏览、寻找突破→由点到面、广泛联系→ Inorganic block diagram inference with a comprehensive strong ability to require high characteristics. The title of the special characteristics of the element compounds as a breakthrough point to the conversion between the material as the main carrier, the basic concepts, basic theory, chemical experiments, simple chemical calculations and other organic combination of examination. Doing a good job in inorganic inference in the third year of senior high school exams can not only deepen our understanding of the related knowledge of elemental compounds, but also cultivate the ability to acquire information, integrate information, analyze problems and solve problems. To solve the general flow of inorganic block diagram inference questions are: the overall view, looking for breakthrough → from point to surface, extensive contact →
